Again, a horse to the face, as I described it, comes down from above and the flexibility in the wrist will lend it whipping power. It doesn't go straight in, bone-to-bone as a Beng would. Also, it's easy to adjust to your opponent's head movements. Granted, it won't hit with as much force as Beng, but it'll hurt badly and your hand won't suffer, either.
I say kick down into his knee and beng him in the stomach.
